APPARATUS FOR SUPPLYING HYDROCARBONS TO METALLURGIC FURNACES.

SPECIFICATION forming part of Letters Patent No. 230,748, dated August 3, 1880. Application led September 11, 1879.

To all whom it may concern Be it known that we, MrLLIs OOVENTRY, the younger, of King street, Manchester, in the county of Lancaster, England, Esq., and MATTHEW WVILKS, of 96 King street, aforesaid, merchant, have invented a new and useful Improvement in Apparatus for Introducing Hydrocarbons into Furnaces in which Metals are Treated, which invention is fully set fort-h in the following specitcation.

Our invention consists in vaporizing hydrocarbon by means of steam in a closed jacket, and then injecting such vapor into thev charge by an air-blast.

Heretofore hydrocarbon has been atomized by steam, which steam was afterward used to inject the spray into the charge, the steam being mingled with the hydrocarbon; and I wish to make a distinction between my process and thosejust mentioned.

In the accompanying' drawing is shown a view, partly in section, representing the device as applied to the trunnions ot' a Bessemer converter. e

About sixteen feet above the level ot' the pipe which conveys the blast to the charge is placed a tank, A, ot'suitable capacity to contain the required amount of petroleum or other hydrocarbon in a tluid state. We prefer to give it a capacity ot' at least one hundred gallons.

On top ofthe tank is a funnel by which it is filled, and at the bottom is a discharge-pipe,

connects with a col1ducting-pipe,G, which extends on a level with the trunnion of the converter, and is tapped through the blast-pipe K opposite the point where such blast-pipe enters the hollow trunnion.

In order to vaporize the tluidhydrocarbon contained in the pipe G, We use the chamber or jacket H, which consists ot' atube surrounding the pipe G and provided With steam inlet and exit pipes I I. As the purpose ot' the steam is simply to vaporize the hydrocarbon, and as it performs none ot' the operation ot' injecting the vapor into the charge, itis closed at the ends and attached to ,the pipe in any suitable manner.

The size ofthejacket, as well as ot' the conducting-pipe, may, of course, be varied accord- 5o ing` to the amount of hydrocarbon required, and the proper relative sizes will readily be learned in practice.

The blast-pipe K enters the trunnion of' the converter and injects the air through tuyeres 55 in the usual manner. A pipe, L, having a cock, M, connects the blast-pipe with the tank A, in order to equalize the. pressure, and such tank is provided with a glass gage to indicate the quantity othydrocarbon contained therein. 6o

enters the blast-pipe and is carried with the blast into the charge. The steam drawn off by the discharge-pipe l.

It will be understood that our device is applicable to other varieties ot' furnaces, the

may be modilication required to adapt it thereto be- 7o ing within the scope ot' our invention.

Having thus described our invention, we l claim- In combination with a receptacle for containing a charge of metal, and an airblast 75 pipe `connected therewith, a tank for containing fluid hydrocarbon, a conducting-pipe from said tank entering said blast-pipe, and a steamjacket having closed ends, the hydrocarbon beine va )orized b f the steam in such closed 8o jacket, and, so vaporized, injected into the charge by the air-blast, as described and shown.
